PBBV is a salmon-colored monke that normally "spawns" on the bridge in the Forest Map. It talks in a "deep, raspy voice". It normally says something along the lines of "PBBV is here. PBBV has become hostile".
There is also a video by chippdbanjo about PBBV named fileproof-appke that starts off totally normal but after probably 1 second the video's colors get more vibrant and then you'll start to hear a text-to-speech-like voice saying an IP address-like number combination and repeating them 2 times (it's shown below here you moron):
